Bring up pavucontrol and remove device 0 from pulsaudio control.
Should be on the last tab.  Then check what happens if you try to play
a .wav file with the command
aplay --device=plughw:0,0  some_wav_file.wav
If it plays, the problem is in the pulseaudio setup / interface with
alsa, because alsa is working, so the correct driver is loaded
and working.
If it seems to be working, but there is no sound, check physical
connections like speakers, because alsa thinks its sending sound to
output.

If the command aborts, then there is a problem with the alsa driver.
That seems unlikely, since aplay showed it correctly.

If you have audacity installed, you can confirm the failure by
importing a sound file into audacity (File->audio_import), and playing
it (space bar). If the meters move, but there is no sound, then the
driver is loaded and functioning, but there is a disconnect at output.

If all the connections are right, it might be that the default device
is device 0,1 (digital), instead of device 0,0 (analog).
